Korg MS-20 mini Monophonic Analog Synthesizer

The Korg MS-20 mini is a faithful recreation of the legendary MS-20 analog synthesizer originally introduced in 1978. Designed under the supervision of the original MS-20 engineers, this compact monophonic synthesizer reproduces the iconic circuitry, aggressive filters, and semi-modular patching architecture that made the original instrument one of the most influential synthesizers in electronic music history.

Reduced to approximately 86% of the original size while preserving its distinctive appearance and sound character, the MS-20 mini delivers authentic analog synthesis for modern producers, performers, sound designers, and synthesizer enthusiasts. From deep basses and screaming leads to experimental soundscapes and evolving textures, the MS-20 mini offers an unmistakable analog sound that continues to inspire musicians worldwide.

Authentic Recreation of the Original MS-20

The MS-20 mini faithfully reproduces the circuitry of the original MS-20, preserving its raw analog character and highly distinctive sonic personality. The instrument retains the aggressive filter response and powerful sound that made the original synthesizer a favorite among electronic musicians, producers, and sound designers.

Every aspect of the instrument has been carefully recreated, from the panel layout and control structure to the legendary filter behavior and patching workflow.

True Analog Signal Path

The synthesizer features a fully analog architecture consisting of:

• 2 Voltage Controlled Oscillators (VCOs)
• 2 Voltage Controlled Filters (High-Pass and Low-Pass)
• 2 Envelope Generators
• 1 Modulation Generator (LFO)
• Voltage Controlled Amplifier (VCA)

The dual-oscillator design supports rich and complex sound creation with multiple waveforms, ring modulation, oscillator mixing, and extensive modulation possibilities.

Legendary Self-Oscillating Filters

One of the defining characteristics of the MS-20 mini is its iconic filter section. The synthesizer incorporates separate resonant high-pass and low-pass filters capable of self-oscillation and dramatic tonal shaping.

The early revision filter design delivers the famous aggressive and slightly distorted analog character that has been widely used in electronic music, film scoring, experimental composition, and modern sound design.

Semi-Modular Patching System

The MS-20 mini includes an extensive patch panel that enables users to reroute signals and create advanced modulation paths using patch cables. The semi-modular architecture encourages experimentation and provides deep synthesis capabilities without requiring external modular equipment.

The patch system allows users to:

• Create custom modulation routings
• Generate complex evolving sounds
• Manipulate oscillator and filter behavior
• Experiment with sample-and-hold functions
• Explore advanced analog synthesis techniques

External Signal Processor (ESP)

The integrated External Signal Processor extends the creative possibilities of the MS-20 mini by allowing external audio sources to interact with the synthesizer engine.

Users can connect instruments such as electric guitars, microphones, drum machines, and external synthesizers to extract pitch and envelope information, enabling unique audio processing and unconventional synthesis applications.

Dedicated Mini Keyboard

The instrument features a custom-designed 37-note mini keyboard spanning three octaves. Despite its compact dimensions, the keyboard provides excellent playability and complements the portable design of the synthesizer.

The keyboard layout makes the MS-20 mini suitable for desktop production environments, mobile studios, and live performance rigs.

Modern MIDI and USB Integration

While preserving its vintage analog architecture, the MS-20 mini incorporates modern connectivity features for integration with contemporary production environments.

• MIDI IN for external control and sequencing
• USB-MIDI connectivity for computer integration
• Headphone output for private monitoring
• Audio output for studio and live performance setups

The USB-MIDI functionality allows musicians to control the synthesizer directly from DAWs and MIDI controllers, combining classic analog sound with modern production workflows.

Compact Design with Vintage Character

The MS-20 mini retains the visual identity of the original instrument while reducing its physical dimensions to approximately 86% of the original size. Every detail, from the panel graphics to the control layout, has been recreated to provide an authentic analog synthesizer experience in a more portable format.
